CAR-ROOF.

SPECIFICATION forming part of Letters Patent N 0. 462,375, datedNovember 3, 1891.

Application filed April 7, 1891. Serial No. 387,942, (No model.)

I To all whom, it may concern:

Be it known that we, RUE L. COUCH and ROBERT OTTERSON, of the city ofSt. Louis, State of Missouri, have invented certain new and usefulImprovements in Cal-Roofs, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

Our invention relates to improvements in car-roofs and it consists inthe novel arrangement and combination of parts, as will be more fullyhereinafter described, and designated in the claims.

In the drawings, Figure l is a top plan view of a car having ourinvention applied thereto with one of the sheets removed. Fig. 2 is anen larged transverse section, taken on the line a; of Fig. 1. Fig. 3 isa transverse section taken through one of the sideribs on the line yy.Fig. at is a perspective view of one of the end sheets, which we employin carrying out our invention. Fig. is a perspective view of the samesheet inverted, and Fig. 0 is a perspective view of a cap which weemploy in carrying out our invention. Fig. 7 is a perspective view ofone of the side ribs. Fig. 8 is an end view of one of the intermediatesheets, show ing one of the bent portions turned upward.

Referring to the drawings, 1 indicates the wooden portion of the roof,which is of the ordinary construction, and 2 the galvanized-i ronsheets, with which we preferably cover the roof. Said sheets are formedas shown in Figs. 4: and 5, the same being provided with upturnedportions 3 and 4 and also with bent portions 5 and G.

7 indicates securing-strips, which are secured to the wooden portion andproject beyond the edges of same, as shown in Figs. 1

and 2, and over these strips the bent portions 5 and 6 of sheets 2 maybe slipped.

8 indicates U-shaped caps, provided wit-h the right-angled portions 9,which portions are secured to the wooden portion of the roof. Said capsare adapted to fit over the upturned portions 4 of sheets 2, as can bereadily perceived by referring to sectional Fig. 3, and also adapted tofit over the upturned portions 3, as can be readily seen by referring toFig. 2. The sheets 2 are all made about the same form throughout theentire roof and are laid on the wooden portion of the roof with theupturned portions 4 running transversely and the upturned portions 3longitudinally with the roof, thereby forming a series of side ribs 10and a longitudinal rib 11.

12 indicates a supplemental cap, which is adapted to be placed over ribs10 and 11 and is secured to the upturned portions of sheets 2, and alsoto pieces 8, by means of rivets or bolts 13, thereby forming a rigid andsubstantial rib. v

From the construction, as hereinbefore stated, it can be readilyperceived that the sheets 2, when located in their normal position onthe roof, cover up all the nail-heads arising from securing strips 7 and8 to the wooden portion of the roof, or, in other words, sheets 2 arenot secured directly to the roof, but are held on the roof by means ofthe strips 7 and 8 and the supplemental caps 12 and rivets 13. Thestrips 7, and consequently the bent portions 5 and 6 of sheet 2, may bebent down on the edges of the wooden portion of the roof, as shown tothe left in Fig. 2, or the same project outwardly, as shown to the rightin said figure. Either form of construction could be used at thediscretion of the builder. The supplemental caps 12 are provided withprojecting portions 14, and the same are bent over the ends of said cap,as shown in dotted lines in Fig. '7, thereby closing the end of saidcap. By the location of the sheets, as hereinbefore described, acontinuous central rib 12 is formed.

15 indicates braces for supporting the roof, the same being providedwith a V-shaped recess 16, adapted to fit over the central rib 11, andwith perforations 17, terminating in square or angular sockets 18. \Vegenerally employ three of these braces for one car. Said braces aresecured to the roof by means of bolts 19. Said bolts are inserted frombelow, pass upwardly through the roof, and secured rigidly to the sameby means of nuts 20.

21 indicates soft metallic washerssuch as lead-which are interposedbetween the exterior surface of the metallic roof and nuts 20. Said nutsare adapted to lit in the square sockets 18, formed in braces 15,whereby they are prevented from working loose. The soft metallic washers21, interposed as hereinbefore described, form a water-tight joint,thereby preventing the access of any water into the interior of the carthrough the perforations in the roof through which bolts 17 areinserted. The braces may also be used as supports for the running-board.In other words, they have two functions: to brace the roof, and also aresupports for the runningboard.

By the construction as herein set forth it can be readily perceived thatthe entire exterior surface of the Wooden portion of the roof isprotected from rain, snow, &c. Even the edges of the same are protectedby means of the drip edges or strips 7 being bent over the same.

Having described the diiferent parts of the roof, it is only necessaryto state that ordinary judgment will suggest the manner of laying thesame anduniting the parts together.

Having fully described our invention, what we claim is 1. Thehereinbefore-described metallic roof, composed of securing-strips 7,adapted to be attached to a suitable support, plates 2, en-

gaged by the said strips, flanges 4 on said plates, strips 8, secured tothe support and having a U shaped portion overlapping flanges 4:, a cap12, covering flanges 4 and strips 8, and rivets passing through the cap,flanges, and strip, substantially as described.

2. The hereinbefore-described metallic roof, composed of a suitablesupport, U-shaped se' curing-strips 8, attached to the upper surfacethereof, plates 2, covering the said support and having flanges 4:,covered by the said securing-strips, a cap 12, covering the said flanges4 and strips 8 and provided with a 4. The combination of theherein-described I metallic roof with braces 15, provided with aV-shaped recess 16, adapted to fit over the central rib of the roof, andangular sockets l8 forlocking the nuts to the retaining-bolts,retaining-bolts passing through the said roof and braces, andsoft'metallic washers 21 for forming a water-tight joint where saidretaining-bolts pass through the roof, substantially as set forth.

5. The herein-described metallic roofing sheet, provided on two adjacentedges with portions 5 and 6, bent parallel with the main portion of theplate, and on the remaining edges With flanges 3 and 4, formed on theopposite side of the sheet to that upon which the portions 5 and 6 arelocated, substantially as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
